INVALID BED.

Application filed May 22,

To all whom it may concern- Be it known that I, 'VVYArr W. ZAoHARY, acitizen of the United States, and a resident of Pine Bluff, in thecounty of Jefterson and State of Arkansas, have invented certain new anduseful Improvements in Invalid Beds, of which the following is aspecification.

This invention relates to beds especially adapted for use by invalids.

An important object of this invention is to provide a bed having novelmeans whereby the patient may be temporarily raised to permit themattress to be withdrawn and changed in its position on the bed, orpossibly replaced by another mattress'without inconvenience ordiscomfort to the patient.

A further object is to provide an invalid b'ed having a mattressprovided with a detachable portion or section which may be withdrawn atany time to provide an opening for the reception of a receptacle.

A further object is to provide an invalid bed having simple meanswhereby the adjustments may be made entirely byone attendant withoutgoing from one end of the. bed tothe other. f

A further object is to provide an invalid bed which is neat inappearance, of highly simplified construction and cheap to manufacture.r

Other objects and advantages 'of the invention will be apparent duringthe course ofthe following description.

In the accompanying drawings forming a part of this application and inwhich like numerals are employed to designate like parts,

through the bed.

and the mattress 9 which is mounted thereon is provided with adetachable section 10 which may be removedtoprovide an openingll for thereception of an article 12. The member 12 may be co-extensive in depthwith the mattress and therefore has its top approximately fiush with thetop of the mattress. When the section 10 is in position in the-openingllthe same may be held against displacement by a holding .strap 14,preferably secured as indicated at 15 to: one side wall of the opening11 and the other end of the strap is provided with an attaching hookformember 16 adapted to be'engaged with a suitableholding member, 17arranged at the other side of the ,opening -When thestrap 1 1 isextended across the outer end of the section 10 the section is securelyheld against displacement and the weightof the, patient cannot force thesection 10 laterally. It will be observed that the outer end of thesection 10 is pro-v vided with a hand strap 1-9.by means of which thesection may be withdrawn or inserted. r

As illustrated in Figure 1 a patient supporting sheet 20 extendslongitudinally of the bed at'a point above the mattress and is providedat its ends with hems for the reception of attaching bars or rods Theconnecting bars or rods 21 have them ends directed laterally to provideattaching hooks 22 which are received inqloops 23 formed at the uppercorners of the sheet supporting frames generally designated by numeral24. The end me'mb'ers'lof the sheet supporting frames 24 are designatedby the numerals f 25 and are provided intermediate their ends with loops27. A I

The loops 27 are mounted on transversely extending pivot pins or bars 28permanently carried by the members 25 of the sheet supporting framesconstitute levers, the upper ends of which have connection with thetransversely extending bars or rods 21. It might be stated that thehooks 22 arecdetaehably received in ends of the bed., Theend the loops23 and the bars 21 may therefore be disconnected when it is desired todetach the sheet. The levers 25 of each sheet supporting frame areformed from the same length of metal and the loops 23 are joined by theconnecting portion 29 arranged slightly in advance of the attaching bar21.

As illustrated in Figure 3 the lower portions of the levers 25 areprovided with loops or eyes 30 to which lower connecting bars or rods 33are joined through the medium of attaching hooks 34. The intermediateportions of the lower rods 33 of which there are two are formed witheyes or loops 36 which are mounted on an operating shaft 37.

Figures 1 and 2 illustrate that the operating shaft 37 is extendedlongitudinally of the bed between the longitudinal edges of: the sameand one end of the shaft is provided with holding members 88 in thenature of nuts. The other end of the shaft 37 is exteriorly threaded forengagement with a hand wheel 40 by means of which the sheet 20 may betensioned when desired. It will be observed that the hand. wheel 40urges a collar or sleeve 41 into engagement with the adjusting loops 36and thereby moves the lower portions of the sheet supporting framestogether. When the hand wheel 40 is turned in one direction the distancebetween the holding members 38 and the collar 41 is decreased so thatthe sheet 20 is tensioned.

When the member 20 is thus tensioned the patient is raised from themattress so that the mattress may be withdrawn laterally and replaced ina different position so that the patient will be rendered morecomfortable. In carrying out the invention the nut 38 may be adjusted onthe shaft 37 for varying the distance between the rod portions of thesheet supporting frame.

Figure 4: illustrates that the lower portions of the levers 25 haveconnection with inclined braces 50 the intermediate portions of whichare looped as indicated at 51 and are slidable on the shaft 37. Thelower rod 38 adjacent the handle is urged into engagement with thecollar 4-1 by means of a coil spring 5 1- confined between the washer 55and a retaining pin 56, the said retaining pin being extended throughthe shaft 37.

Of course,the sheet 27 which is constructed from a suitable stoutmaterial is provided with an opening 58 in alignment with the opening11.

In operation the patient in the bed may be raised slightly bysimultaneously increasing the distance between the attaching bars 21.This permits the mattress to be freely removed and reinserted in achanged position, or if desired a new mattress may be substituted. Whenthe strap 14 is extended from the detachable section 10 and secured tothe member 17 the entire mattress and the sec tion 10 may be removed asa unit and the section will not drop out.

I With reference to the foregoing description taken in connection withthe accompanying drawings, it will be apparent that an invalids bedconstructed in accordance with this invention will permit the member 12to be placed in position without inconvenience on the part of theoperator, and when the said member is in position it is entirelyconcealed.

It is to be understood that the form of the invention herewith shown anddescribed is to be taken as a preferred example of the same and thatsuch minor changes in atrangement and construction of parts may be madeas will remain within the spirit of the invention and the scope of whatis claimed.

Having thus described the invention, what is claimed is 1. Aninvalid'bed comprising a head, and a foot, pairs of levers arranged atthe ends of the bed, pivot rods extending through the intermediateportions of said levers and connected to the head and foot of the bed,attaching bars having their ends detachably connected to the upperportions of said levers, a sheet connected to said attaching bars, upperand lower bars connected to the ends of said levers, the intermediateportions of said lower bars being formed with loops, a shaft extendingthrough said loops, a holding member threaded on one end of said shaftand means arranged on the other end of said shaft and forming a means toswing said levers and to tension said sheet.

2. An invalid bed comprising a head, and a foot,- pairs of leversarranged at the ends of the bed, pivot rods extending through the 105intermediate portions of said levers and connected to the head and footof the bed, attaching bars having their ends detachably connected to theupper portions of said levers, a sheet connected to said attaching 110bars, upper and lower bars connected to the ends of said levers, theintermediate portions of said lower bars being formed with loops,

a shaft extending through said loops, a holding member threaded on oneend of said 115 shaft and means arranged on the other hand of said shaftand forming a means to swing said levers, and bracing devices connectedto the lower ends of said levers and having loops slidable on saidshaft.

3.
